HORRIBLE EXPERIENCE!!

I BOUGHT A VEHICLE AT THE END OF OCTOBER WITH ONLY 62K ON THE CLOCK. FROM WEBUYCARS. THIS WAS A DEKRA APPROVED VEHICLE. A MONTH LATER THE TIMING BELT SNAPPED & MY ENTIRE ENGIN IS NOW DAMAGED. A DEKRA ASSESOR IS SUPPOSE TO HAVE GONE OUT TO ASSESS WITHIN 24-48HOURS. IT HAS BEEN 72 HOURS AND WHEN WE CALL, WE ARE INFORMED THAT THEY ARE STILL TRYING TO GET HOLD OF THE ASSESOR. THIS IS ABSOLUTELY RIDICULOUS. IVE BEEN WITHOUT A VEHICLE FOR 4 WEEKS AND THERE IS ABSOLUTELY NO SENSE OF URGENCY TO ASSIST ME....
